If you share your home with furry friends, you are likely familiar with the “Saturday Morning Ritual.” No, not cartoons—I’m talking about sitting on the floor with a pair of scissors, surgically removing a tight cylinder of matted dog hair from your vacuum’s roller brush. It is messy, frustrating, and frankly, gross.
The Shark Navigator Lift-Away ZU503AMZ claims to end that ritual forever. Boasting a “Self-Cleaning Brushroll” and Shark’s signature Lift-Away technology, this teal powerhouse is marketed as the ultimate mid-range solution for pet owners and allergy sufferers.
But does the non-stop hair removal technology actually work, or is it just marketing fluff? We took a deep dive into the ZU503AMZ to see if it can handle the chaos of a multi-pet household without losing suction—or its mind.
Key Features and Benefits
1. The Star Show: Self-Cleaning Brushroll
The headline feature of the ZU503AMZ is the self-cleaning brushroll. Unlike standard bristle brushes that trap long hair, Shark uses a unique comb-like design behind the roller. As the vacuum cleans, the comb actively separates hair from the bristles and sends it directly into the dust cup.
For households with Golden Retrievers, Maine Coons, or humans with long hair, this is a game-changer. It maintains performance because a clogged brushroll typically stops spinning or loses agitation power.
2. Lift-Away Versatility
Upright vacuums are great for floors but terrible for everything else—usually. Shark’s “Lift-Away” functionality allows you to detach the main canister pod from the floor nozzle. With the push of a button, you are holding a lightweight portable vacuum that can easily travel up stairs, clean blinds, or reach cobwebs on the ceiling.
3. Anti-Allergen Complete Seal & HEPA
Many budget vacuums pick up dirt but spew fine dust back into the air through exhaust vents. The ZU503AMZ features a completely sealed system paired with a HEPA filter. This combination captures and traps 99.9% of dust and allergens inside the vacuum. If you sneeze while cleaning, this feature alone makes the Shark worth the investment.

While many cordless vacuums struggle to break the 500W mark, this corded upright draws a full 1200 Watts. This raw power provides deep carpet agitation and strong suction for hard floors, ensuring that heavy debris like kitty litter isn’t just scattered around.
Hands-On Experience: Performance in the Real World
Maneuverability and Weight
Weighing in at around 15 lbs, the ZU503AMZ isn’t a featherweight stick vacuum, but the Swivel Steering makes it feel much lighter in motion. A quick twist of the wrist allows the head to snake around furniture legs and glide into corners. However, the bulk of the motor is lower on the unit, which provides stability but can make it feel slightly heavy when pulling it back on thick carpet.
The “Hair Wrap” Test
This is where the rubber meets the road. In testing against significant amounts of pet hair, the self-cleaning roll performed admirably. While it isn’t magic—you might occasionally see a stray strand—it vastly outperforms standard brush rolls. The hair is consistently sent to the dust cup rather than wrapping around the bar.
Above-Floor Cleaning
Transitioning to the Lift-Away mode is intuitive. The included Upholstery Tool is excellent for removing fur from sofas, while the Pet Crevice Tool is long enough to get between cushions or behind heavy furniture. The suction remains strong even when using the hose, which isn’t always the case with uprights.
Pros and Cons
| ✅ The Good | ❌ The Bad |
|---|---|
| Zero Hair Wrap: The self-cleaning brushroll actually works as advertised. | Top Heavy: When the pod is attached, it can tip over if left standing while using the wand. |
| Sealed HEPA System: Excellent for keeping air quality high. | Corded: You are tethered to the wall (though the cord is a decent 25ft). |
| Lift-Away: Makes cleaning stairs and curtains effortless. | Small Bin: The dust cup is smaller than some other full-size uprights. |
| Strong Suction: 1200W motor pulls deep dirt from carpets. |
